// I2Cdev library collection - MPU6050 I2C device class, 6-axis MotionApps 2.0 implementation
// Based on InvenSense MPU-6050 register map document rev. 2.0, 5/19/2011 (RM-MPU-6000A-00)
// 5/20/2013 by Jeff Rowberg <jeff@rowberg.net>
// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
//
// Changelog:
// 2019/07/08 - merged all DMP Firmware configuration items into the dmpMemory array
// - Simplified dmpInitialize() to accomidate the dmpmemory array alterations
// ... - ongoing debug release

NOTE: Arduino v1.0.1 with the Leonardo board generates a compile error

The solution requires a modification to the Arduino USBAPI.h file, which
is fortunately simple, but annoying. This will be fixed in the next IDE
release. For more info, see these links:

// I2Cdev library collection - MPU6050 I2C device class, 6-axis MotionApps 2.0 implementation
// Based on InvenSense MPU-6050 register map document rev. 2.0, 5/19/2011 (RM-MPU-6000A-00)
// 5/20/2013 by Jeff Rowberg <jeff@rowberg.net>
// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
//
// Changelog:
// 2019/07/08 - merged all DMP Firmware configuration items into the dmpMemory array
// - Simplified dmpInitialize() to accomidate the dmpmemory array alterations
// ... - ongoing debug release

// I2C device class (I2Cdev) demonstration Arduino sketch for MPU6050 class using DMP (MotionApps v2.0)
// 6/21/2012 by Jeff Rowberg <jeff@rowberg.net>
// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
//
// Changelog:
// 2019-07-08 - Added Auto Calibration and offset generator
// - and altered FIFO retrieval sequence to avoid using blocking code
// 2016-04-18 - Eliminated a potential infinite loop
// 2013-05-08 - added seamless Fastwire support
// - added note about gyro calibration
// 2012-06-21 - added note about Arduino 1.0.1 + Leonardo compatibility error
// 2012-06-20 - improved FIFO overflow handling and simplified read process
// 2012-06-19 - completely rearranged DMP initialization code and simplification
// 2012-06-13 - pull gyro and accel data from FIFO packet instead of reading directly
// 2012-06-09 - fix broken FIFO read sequence and change interrupt detection to RISING
// 2012-06-05 - add gravity-compensated initial reference frame acceleration output
// - add 3D math helper file to DMP6 example sketch
// - add Euler output and Yaw/Pitch/Roll output formats
// 2012-06-04 - remove accel offset clearing for better results (thanks Sungon Lee)
// 2012-06-01 - fixed gyro sensitivity to be 2000 deg/sec instead of 250
// 2012-05-30 - basic DMP initialization working

NOTE: In addition to connection 3.3v, GND, SDA, and SCL, this sketch
depends on the MPU-6050's INT pin being connected to the Arduino's
external interrupt #0 pin. On the Arduino Uno and Mega 2560, this is
digital I/O pin 2.

/* =========================================================================
NOTE: Arduino v1.0.1 with the Leonardo board generates a compile error
when using Serial.write(buf, len). The Teapot output uses this method.
The solution requires a modification to the Arduino USBAPI.h file, which
is fortunately simple, but annoying. This will be fixed in the next IDE
release. For more info, see these links:

# flutter_app_esp32_ble_mpu6050
A new Flutter application.
## Getting Started
This project is a starting point for a Flutter application.
A few resources to get you started if this is your first Flutter project:
- [Lab: Write your first Flutter app](https://flutter.dev/docs/get-started/codelab)
- [Cookbook: Useful Flutter samples](https://flutter.dev/docs/cookbook)
For help getting started with Flutter, view our
[online documentation](https://flutter.dev/docs), which offers tutorials,
samples, guidance on mobile development, and a full API reference.

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

description: A new Flutter application.
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg

# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
